vssource 0.11.1

Vapoursynth Wrapper for DVDs stuff

vs-source

DVDs were an error, but can be nice to use with this package.

A wrapper for DVD file structure and ISO files.

For support you can check out the JET Discord server.

How to install

Install vssource with the following command:

pip install vssource

Or if you want the latest git version, install it with this command:

pip install git+https://github.com/Jaded-Encoding-Thaumaturgy/vs-source.git

One of these plugins is required:

• dvdsrc2
• d2vSource and either DGIndex or patched d2vwitch

DGIndex is recommended over d2vwitch as the latter has various problems.

It can also be used under linux with wine; notice that doing it requires binfmt and dgindex in PATH.

chmod +x DGIndex.exe
sudo ln -s $(pwd)/DGIndex.exe /usr/bin/dgindex

Optional dependecies:

• dvdsrc_dvdnav_title_ptt_test to automatically check the chapters against libdvdnav.

• dvdsrc to automatically double-check the determined dvdstrucut agaist libdvdread.

• mpv to determine chapter splits by loading the DVD and hitting I or using it like this:

  mpv --dvd-device=<iso> dvd://<title>
  # mpv titles are zero-indexed
  # vssource titles indices start from 1
  # sometimes it is useful to to scale the osc down
  # --script-opts=osc-scalewindowed=0.4,osc-scalefullscreen=0.4
  

  Related to mpv, the mpv-dvd-browser plugin can be useful for this too.

Getting a vs.AudioNode and demuxing AC3 requires dvdsrc2

The only codecs offically supported are: stereo 16bit LPCM and AC3

Usage

After installation, functions can be loaded and used as follows:

from vssource import IsoFile, D2VWitch, DGIndex
from vstools import set_output

# Autodetect what to index with
iso = IsoFile('.\DVD_VIDEOS\Suzumiya_2009_DVD\KABA_6001.ISO')

# Force index with dgindex
iso = IsoFile('.\SOME_DVD_FOLDER\HARUHI', indexer=DGIndex)

title1 = iso.get_title(1)

# prints audio and chapter information
print(title1)

title1.video.set_output(0)
title1.audios[0].set_output(1)

title1.dump_ac3('full_title.ac3', 0)

# -1 is replace with end i.e 15
ep1, ep2, ep3 = title1.split_at([6, 11])
ep1, ep2, ep3 = title1.split_ranges([(1, 5), (6, 10), (11, 15)])
ep1           = title1.split_range(1, 5)
ep2           = title1.split_range(6, 10)
ep3           = title1.split_range(11, -1)

# preview your splits
title1.preview(title1.split_at([6,11]))

ep1 = title1.split_range(1,5,audio=0)

print(ep1.chapters[:-1])

set_output([
    ep1.video,
    ep1.audios[0],
])

a = ep1.ac3('/tmp/ep1.ac3',0)
# a is in seconds of how much samples are there too much at the start

## Advanced Usage

# Remove junk from the end
title1 = iso.get_title(1)
title1.chapters[-1] -= 609
title1.preview(title1.split_at([7, 12]))


#--------

splits = []
# title 2 through 5 containe episodes
# remove 'junk' from beginning
# you can quickly check with preview
for a in range(2,6):
    t = iso.get_title(a)
    t.chapters[0] += 180
    splits += [t.split_at([])]
    t.preview(splits[-1])

print(splits[0].ac3('/tmp/ep1.ac3'))
# 0.019955555555555556

#--------

# multi angle + multi audio + rff mode
# japanese
a = iso.get_title(4, angle_nr=1, rff_mode=2).split_at([5, 10, 15],audio=1)

# EP 1 japanese
a[0].video.set_output(0)
a[0].audios[0].set_output(1)

# italian
b = iso.get_title(4, angle_nr=2, rff_mode=2).split_at([5, 10, 15],audio=0)

# ep 2 italian
b[1].video.set_output(0)
b[1].audios[0].set_output(1)

The Title.split_at method should behave just like mkvmerge chapter splits (split before the chapter, first chapter is 1), so if you want the (first chapter, all other chapters after) 2.

Output chapters always start with frame zero and end one past the last frame. This has been chosen because it allows you to change the video boundries and for example cut stuff off from the end. Thats in contrast to how dvd chapters work as their only supposed to be points you jump to.
